This is a physics question, I selected physics but it shows
chemistry here, somehow......

The group I element potassium (K) forms the bcc crystal structure with the cubic-lattice parameter a=0.533 nm. Each atom contributes 1 electron to the conduction band. (a) Calculate the number of electrons per m-3 in the conduction band for potassium. (b) Calculate the Fermi energy for potassium in units of eV. The figure below shows the Brillouin Zone (the reciprocal cell) for the bcc crystal that corresponds to potassium. ky Direction Spacing IN ГР узи ΓΗ 2x P Hky IN ky (c) Does the Fermi sphere for potassium fit completely inside the Brillouin Zone? Ensure you explain the reason for your answer. (d) What is the impact on electrical conductivity if the Fermi sphere DOES fit inside the Brillioun Zone?
